LOOSE-LEAF BOOK.

Specification of Letters Patent.

Patented Aw. 12,1913.

Application led February 3, 1913. Serial No. 745,870.

To all 'wh-0m t may concern Be it known that I, FRANK E. HoUsH, acitizen of the United States, residing at vWinthrop, in the county ofSuffolk and State of h/Iassachusetts, have invented newI and usefulImprovements in Loose -Leaf Books, of which the following is aspecification.

My invention is an improvement in loose leaf books, designed to reducethe cost of production while improving the quality of the finishedarticle.

In the drawings: Figure 1 is a plan view of a loose leaf, made accordingto my invention; Fig. 2 is a plan view of a loose lea-f, a second leafin reversed position being indicated underneath; Fig. 3 is an edge viewof the sheet of Fig. 1; Fig. l is a perspective end view of Fig. 1looking in the direction of the arrow; .F ig. 5 shows an irregularcrimped pattern, and Fig. 6 shows a stack of leaves, assembled to form abook.

I have shown my invention as applied to the loose leaf book of myLetters Patent of the United States, No. 1,029,369, dated J une 11,1912, but it is4 obvious that it may be applied to other loose leafbooks.

My invention is especially applicable to loose leaf books designed foruse as postcard albums or scrap-books, in which the articles to be filedare pasted or otherwise secured upon the surface of the leaves. It isobvious that. in doing this the leaf is in effect thickened, and unlessproper provision is made, as the book fills, the unbound end of the bookwould become much thicker than the back or bound end. It has beencustomary heretofore to pro-vide for thisy condition by insertingbetween the leaves at t-he back or binding edge, filling strips whichthickened the back of the book and thus allowed for the graduallyfilling and thickening of the front of the book as the photographs,post-cards or clippings were secured upon the leaves. The use of thesefilling strips is a source of expense in making and assembling thebooks, if the strips are secured to the base of the leaves by paste orthe like, and of trouble in use if they are not.

In my invention the binding end of each leaf of the loose leaf book ispassed between dies and subjected to pressure, thinning and extendingthe paper and folding the excess in size thus formed in waves or crimpsas shown in Figs. 1, L1 and 5, these waves extending beyond the plane ofthe leaf. In the form shown in Fig. 1, the crimps are oblique to theedges of the leaf and in use, every other leaf, is, in the process ofassembling a stack of leaves to form a book, reversed, the object beingto cause the waves or crimps of each leaf to cross the waves or crimpsof the adjacent leaves and thus to prevent the crimps on one leaf fromfitting or nesting into the crimps on the adjacent leaf and thus, to agreater or less extent, neutralize theeffect desired. This matter isillustrated in Fig. 2 and indicates the easiest and cheapest methodknown to me of attaining the desired end, namely, to reverse every otherleaf, in the assembling, causing the crimps to cross each other andpreventing nesting. But the end can of course be attained by usingdifferent or irregular crimpings on adjacent sheets, as, for example,the crimpings on one sheet might be parallel with the sides of thesheet, while tho-se on the adjacent sheet might be parallel with theends of the sheet.

In the drawings A indicates the leaf; o, the binding end, suitablyslotted at b to re ceive binding and securing devices, while the wavesor crimps are marked o.

In the modified form shown in Fig. 5, the irregular crimps orindentations are marked cx.

I claim z- 1. The loose leaf book above described, made up of a stack ofloose leaves, each leaf being of one integral piece, thickened at itsbinding end by indenting the material of the leaf, the indentations onadjacent leaves being non-Corresponding, to prevent the nesting of theindentations on adjacent leaves.

2. The loose leaf book above described, made up of a stack of looseleaves, each leaf being o-f one integral piece, thickened at its bindingend by crimps oblique to the edges of the leaf and assembled with thecrimps in adjacent sheets in crossed relation.

Signed by me at Boston, Massachusetts, this 29th day of January, 1913.
